Question

The function f is defined by f(x) = 3x-7/8.

(1) Evaluate f(-2) and f(2 5/6).
(2) final the value of x for which f(x)=5

Answer 1

-55/8, 61/8, x=47/24

Explanation:

not sure if you meant f(25/6) or f(2 5/6), I just assumed it was the second one

but basically just sub in the value into the eqn given
